I made this out of two doors and some scrapped MDF quite a few years back now and I've been using it to store sheets and blankets etc. I'll be sad to say goodbye but I just don't really need it now I have more inbuilt storage. I put a foam top on at the time so it can double as a seat. It's very much a DIY job and it's not perfect, probably needs a coat of paint but it's still pretty sturdy actually; I regularly stand on it to reach the shelves. It's not too heavy either. It's 45cm deep, 70 high, 70 long.
